.To aZZ' whom i may concern:

Be It known that I, G. W. MITCHELL, of

Jackson, in the county of Madison and State of Tennessee, have inventeda new and useful 'Sewing-Machine Shuttle, and I do hereby declare thatthe following is afull and exact dei scription. thereof, reference beinghad tothe accompanying drawings, and to the letters of reference markedthereon.

lThe nature of my invention consists in the construction of the shuttleof a sewing-machine and the position of its bobbin. i p ,y To enableothers skilled in the art to make and use my invention, I will proceedto del` scribe its construction and operation.

.ing a curved point, as shown in Figs. 4 and 7, on the side ofthe-cavity a't a, Figs. 4 and 7 5 f .and connecting with the curve orhollow in the Qpcint" of the shuttle is a slot, a, which allowsI y thethreadtopass from the bobbin,without any break or angle, through thehole nearestthe 'point oftheshuttle; then passing through other holes togive fpropery` tension, as shown at b in Fig. 3, and thereby avoidingthe evil AattendA ing the' operation of other shuttles, whichhave Ya-lateral drag on the bobbinwhenfthe thread is paying off at the end ofthe` bobbinwhich causes uneven tension,` The bobbin is formed f withheads to t thecavity of the shuttle, the` heads forming `part-of thesides ofthe shuttle, and is kept in position by the sides of the shuttlerace or` carrier.

What I ,claim` as my invention, and desire i to secure byLetters Patent,isf- The` shuttleformed `with an open ,cavltyA through it in fatransverse "direction to its Inove-` vment, with abobbin t`the cavity,the heads of the bobbin formingfa part or' the sideslofthc shuttle, andbeing keptinposition by the sides l of the shuttle race or; carrier,substantially `as described andset forth; 1
